Error: cannot find symbol variable LOLLIPOP

I have seen many examples in different android libraries about detecting if device is LOLLIPOP supported or not. But when I use it in my app, it is throwing the following error:

Error:(20, 60) error: cannot find symbol variable LOLLIPOP

For example my source code is:

static boolean isLollipop() {
    return Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP || Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP_MR1;
}

I am using the latest version of Android Studio with all packages updated and installed.

Error is on this statement:

Build.VERSION_CODES.LOLLIPOP

Also when I check options of VERSION_CODES, LOLLIPOP does not exist in that list.

If androidx and androidx-adapter plugins are already added then you have to remove these plugins. The trick is to add the platform before adding these plugins back in your project.

You will have to remove the platform if it is already added.

ionic cordova platform rm android
ionic cordova plugin rm cordova-plugin-androidx
ionic cordova plugin rm cordova-plugin-androidx-adapter

After removing these things from your project, you can add the platform (android in this case) and then you will have to add the plugins to resolve this issue.

ionic cordova platform add android
ionic cordova plugin add cordova-plugin-androidx
ionic cordova plugin add cordova-plugin-androidx-adapter

After following these steps, simply build the project and the errors will be gone!

For last few days, I was struggling with above error with latest cordova-android version 9.0.0

ionic cordova plugin add cordova-plugin-androidx-adapter

Finally, the issue got resolved by installing above plug-in.

 android {
compileSdkVersion 26           //THIS GUY
buildToolsVersion "26.0.2"    //THIS GUY

defaultConfig {
    applicationId "com.example.piotr.myapplication"
    minSdkVersion 15
    targetSdkVersion 23     //THIS GUY
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

 dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

it seems to that you're using old build tools or you're missing some libraries.

I pasted your code into my Android Studio and it works.

Please compare your build.gradle with this one:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23           //THIS GUY
    buildToolsVersion "23.0.2"    //THIS GUY

    defaultConfig {
        applicationId "com.example.piotr.myapplication"
        minSdkVersion 15
        targetSdkVersion 23     //THIS GUY
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1' //THIS GUY
    compile 'com.android.support:design:23.1.1'
}

I've already matched parts which might be important to your code.

Hope it help
